Q:

studying enzyme kinetics encounter formulas of the form f(x) = (K/V)x+1/V, where and are constants. Use this infombon to answer parts and (b). (a) If f(x) = 0.9x + 10, find K and V so that f(x) may be written in the form f(x) = (K/V)x+ 1/V. (b) Find the x-intercept and y-intercept of the line y - (K/V)x+1/V (in terms of K and V). (a) K= (Simplify your answer. Type an integer or a fraction.)

Answer:a) Β K = 0.09, V = 0.1b) [tex]y-intercept= \displaystyle\frac{1}{V}[/tex][tex]x-intercept= -\displaystyle\frac{1}{K}[/tex]Step-by-step explanation: We are given that:[tex]f(x) = \displaystyle\frac{K}{V}x + \displaystyle\frac{1}{V}[/tex]a) If we compare the above equation with the given equation:[tex]f(x) = 0.9x +10[/tex], then, we get:[tex]\displaystyle\frac{1}{V} = 10\\\\V = \displaystyle\frac{1}{10} = 0.1\\\\\displaystyle\frac{K}{V} = 0.9\\\\K\times \displaystyle\frac{1}{0.1} = 0.9\\\\K = 0.09[/tex]K = 0.09, V = 0.1b) [tex]f(x) = \displaystyle\frac{K}{V}x + \displaystyle\frac{1}{V}[/tex]y-intercept is the value when x = 0. Putting x = 0,[tex]y-intercept= \displaystyle\frac{1}{V}[/tex]x-intercept is the value when y = 0. Putting y = 0, we get,[tex]0 = \displaystyle\frac{K}{V}x + \displaystyle\frac{1}{V}\\\\x = \displaystyle\frac{V}{K}\times -\displaystyle\frac{1}{V}\\\\x = -\displaystyle\frac{1}{K}[/tex]
